1. Eliminated backward rotary drilling rig equipment, sales continued to increase

In fact, the so-called new infrastructure is more focused on urban areas, but many cities in urban areas have clear and strict restrictions on vehicle exhaust, so many rotary drilling rig equipment can not work in the city due to exhaust, which is in conflict with new infrastructure projects. Therefore, as a rotary drilling rig company, we have to eliminate the old equipment and replace a batch of new rotary drilling RIGS, which has created a continuous increase in sales of rotary drilling RIGS in recent years.

2. The number of engineering projects increased and the number of rotary drilling rig companies increased

3. The future direction may be biased towards rural areas
